When it is put together, a steel plate of 70 x 10 mm is inserted between these two profiles. To anchor them in the concrete, these profiles are fitted on bo

th sides with anchor bolts ø10 and 125 mm long, which are automatically welded on, every 200 mm with upset butt welding. In the HC-Delta + and Sinus Slide® range, the anchor bolts are welded to the top and bottom as standard. HC-Delta + HC-Delta Sinus Slide® The profiles are connected with wing bolts with plastic nuts that should not be removed after installation. When installing at the yard, the steel plate, which protrudes by 15 mm, is inserted into the previous profile, to achieve a perfect join. The profile is manufactured in standard lengths of 3 m and is available in heights of between 120 and 300 mm. We supply customised solutions from 300 mm upwards. Due to their continuous form, these profiles prevent stress concentrations during the load transfer. Compared with discontinuous profiles, this means a better load transfer can be achieved.

hcjoints.be www.hcjoints.eu HC-Delta (+) (SinusSlide®) Expansion joint for industrial floor Technical sheet Description The patent pending Sinus Slide® joint with corrugated upper side in 5 mm thick steel ensures continuous support of passing wheels regardless of the direction, size and form of the wheel, from the placement of the joint to its maximum opening of 20 mm. By neutralising the striking impact of the wheels, forklift drivers experience unprecedented comfort. At the same time, maximum edge protection and load transfer are achieved, significantly reducing the chance of damage to the floor, the vehicle, or the goods being transported. This Sinus Slide® solution is especially recommended in thoroughfares and/or other areas of the floor that experience high forklift traffic. The Sinus Slide® Joints enables not only joint free floor slabs but the whole floor is experienced as Joint free. You can still see a joint but you don’t feel it anymore. This is a new age in indust

rial flooring technology. This shock-and vibration free crossing will prevent any damage on your floor and save the investor huge amounts on wear and tear of forklifts. Only with the replacement costs of wheels the payback period of the investment is less than one year.

When drying the poured concrete, the inevitable shrinkage is compensated for by the horizontal expansion of the HC-Delta (+) (Sinus Slide®) dilatation joint. This prevents cracks caused by the drying process. This cracking also occurs if the floor has been cut into too late, which is superfluous when fitting an expansion joint.  Preventing vertical movement. The minuscule tolerance between the profiles and the

connection with the 70 x 10 mm steel plate prevents any vertical movement between the various parts of the floor. The steel profiles also ensure the elastic behaviour of the joint.  Load transfer With forklift traffic, the HC-Delta expansion joints provides a transfer of loads from one floor section to another. This means that the floor is less subject to wear, the chance of damage is reduced, and the lifetime of the industrial floor is lengthened considerably. The Sinus Slide® version realize this load transfer is a noiseless and smoothly way. The wheels of the forklifts are sliding shock- and vibration free from one floor section to another. This creates an unprecedented level of comfort.  Maximum load The rigid steel structure ensures that the floor can withstand maximum load with minimum distortion.  Edge protection. The 5 mm thick steel profiles and especially the Sinus Slide® solution give maximum edge protection. The Sinus Slide® solution will not only create an unp

recedented level of comfort but will also avoid any crumbling of the edges of the floor sections.  Easy installation and compatible. The HC-Delta expansion joints are quite easy and quick to install according to the installation instructions given below in this technical documentation. The HC-Delta (+) is 100% compatible with the HC-Delta Sinus Slide® Joint for almost every available height.  Concrete formwork The HC-Delta profiles are fitted according to a layout plan with limited dimensions separating the various floor parts. The areas can then be poured and finished according to the day’s schedule.  Compliant with the European directive 2002/44/EC. The Sinus Slide® solution guarantees shock- and even vibration free transfer between two floor sections even with forklifts with very small and hard wheels. With this feature the HC-Sinus Slide® Joint is compliant with the European directive 2002/44/EC concerning exposures of workers to whole body vibrations. Technische fic

This characterises the position of the load in relation to the joint and support.  Fv= P x (L-A) L o A second factor is the size of the load in relation to the thickness of the floor. Load transfer is only realised from the moment that the load is great enough to move or distort the floor part until any play between the parts is eliminated. Small load Large load o A third factor that influences load transfer is the foundation. If the foundation is solid, the loads will be supported by the foundation. If the floor is on bearing piles, the entire load has to be

borne by the profile. Unstable foundation Solid foundation If a load hits the edge of a plate, then the concrete tensions are roughly 50% higher than when a load is in the middle of the plate. The dilation joint compensates for this increase in height and, depending on the foundation and the position and size of the load, will transfer this load to the adjoining plate.

Test set-up It was decided to test the joint without support to maximise the load transfer through the joint. The joint was fitted into a test specimen measuring 1 m x 1.05m. The joint opening measured 10 mm or 20 mm. For the concrete, one test was conducted with unrein

forced concrete (c30/37) and another with glass fibre-reinforced concrete with 45 kg fibre/m³.
